Design and development of solar powered, bluetooth controlled seed metering mechanism

A solar-powered, Bluetooth-controlled seed metering mechanism is developed to make the machines sustainable and easy to use. Using Bluetooth devices like smart phones reduces the cost of machines and gives a high yield. It replaces the fuel-powered seed metering mechanism, which has lots of environmental problems and labour costs. In a developed machine, the machine is powered by solar energy, which is stored in a battery. At the same time, the machine's motors are rotating using this power, and directions are controlled by Bluetooth devices like a smart phone. For the travel of the machine, we used two DC motors and direction control. The front wheels are connected to a bearing, and where the rear wheel movement is high or rotation is high, the front wheel rotates that side. For the metering mechanism, we used a metallic geared servo motor 360, which is controlled by an Arduino UNO using a Bluetooth module. Chickpea is metered using this machine and gave 83% field efficiency, 0.48 and 0.40 hac/hr theoretical and actual field capacity.
